Seized handbrake lever on rear caliper...

[Peter Berrevoets]

Using the rear brakes from an avant will give you ventilated disks on back.
Calipers and carriers from an avant or early V8 will work but the rotors
must be avant - quattro. The real bugger is that the sliders are not
available separately from the carriers and if those are siezed and in bad
shape, new seems to be the only solution.
